High accuracy measurement

A red semiconductor laser is used as the emitting device and CCD is used as the receiving device. An ideally parallel optical beam is emitted achieving highly accurate measurement.

FDA standard conforming

FDA standard (Class II) conforming model LD-601 is available.

Optical alignment not required

Troublesome optical beam alignment is not required since the emitter and the receiver are mounted on one body.

Safety countermeasures not required

Safety countermeasures, such as protective gear, etc., are not required since LD-600 uses a Class 1 laser as per JIS standards, and LD-601 uses a Class II laser as per FDA standards.

Stable sensing

Shading correction function which compensates for receiver sensitivity variation and generates a uniform sensitivity distribution has been incorporated. Stable sensing over extended periods of time is possible.

Various applications

The sensor can be used for various applications with its binary data output with four different sensing modes.

1. Width measurement / Dark mode
The first dark region from the lower side of the measurement region is measured.

2. Width measurement / Light mode
The first light region from the lower side of the measurement region is measured.

3. Edge measurement / Dark mode
The first dark edge from the lower side of the measurement region is sensed and the width from the dark edge to the upper side of the measurement region is measured.

4. Edge measurement / Light mode
The first light edge from the lower side of the measurement region is sensed and the width from the light edge to the upper side of the measurement region is measured.
